4. What is value?
Value - A capability provided to a customer at the right time
at an appropriate price, as defined by the customer.
• Cost
• Quality
• Delivery

5. What isWaste?
• Waste is any activity that consumes time,
resources, or space but doesn't add any value to
the product or service.

6. • Specify value :
Specify value from the standpoint of the end customer.
•
Identify all the steps in the value stream for each product
family, eliminating whenever possible those steps that don't
create value.
5 principles of lean

7. • Create flow :
Make the value-creating steps occur in tight sequence so the
product will flow smoothly toward the customer.
• Let the customer pull product through the value stream
Make only what the customer has ordered.
5Principles of lean

8. • Seek perfection :
As value is specified, value streams are identified,
wasted steps are removed, and flow and pull are
introduced, begin the process again and continue it until
a state of perfection is reached in which perfect value is
created with no waste.

10. Four Goals of lean
• Improve quality:
In order to stay competitive in today’s
marketplace, a company must understand
its customers' wants and needs and design
processes to meet their expectations and
requirements.
• Eliminate waste:
Waste is any activity that consumes time,
resources, or space but does not add any
value to the product or service.

11. • Reduce time:
Reducing the time it takes to finish an
activity from start to finish is one of the
most effective ways to eliminate waste and
lower costs.
• Reduce total costs:
To minimize cost, a company must produce
only to customer demand. Overproduction
increases a company’s inventory costs due
to storage needs.
Four Goals of lean

Producing more/sooner than the Internal or
External customer needs.

information, machinery or materials.
• Transportation :

Excessive storage and delay of information
or products.
